How can I use TEISER?

IGET: Use TEISER online

A limited version of TEISER is available as part of IGET, an integrated platform for exploring large-scale gene expression and protein behavior dynamics. However, we strongly recommend downloading and using TEISER in house as it requires access to multiple nodes and computational power to complete the jobs in a reasonable time.

Use IGET to discover motifs, pathways, and interactions.

TEISER can be downloaded and used as a command line program (on a Unix or Cygwin machine).

TEISER comes with pre-packaged sequence data for a number of organisms:
human (H. sapiens; 5' & 3' UTRs),
mouse (M. musculus; 5' & 3' UTRs),
yeast (S. cerevisiae; upstream & downstream sequences)

If your favorite organism is not in the list and you would like us to add it, please contact us. You can also add your own organisms (see tutorial or contact us for more details).

TEISER (for Tool for Eliciting Informative Structural Elements in RNA) is a robust and powerful framework for discovering post-transcriptional regulatory elemenets. Click here for a tutorial on how to install and use TEISER.
